Variations in the open-circuit voltage (V ) of ternary organic solar cells are systematically investigated. The initial study of these devices consists of two electron-donating oligomers, S2 (two units) and S7 (seven units), and the electron-accepting [6,6]-phenyl C71 butyric acid methyl ester (PC BM) and reveals that the V is continuously tunable due to the changing energy of the charge transfer state (E ) of the active layers. Further investigation suggests that V is also continuously tunable upon change in E in a ternary blend system that consists of S2 and its corresponding polymer (P11):PC BM. It is interesting to note that higher power conversion efficiencies can be obtained for both S2:S7:PC BM and S2:P11:PC BM ternary systems compared with their binary systems, which can be ascribed to an improved V due to the higher E and an improved fill factor due to the improved film morphology upon the incorporation of S2. These findings provide a new guideline for the future design of conjugated polymers for achieving higher performance of ternary organic solar cells.

The discovery of new structures is very important for metal-organic framework (MOF) adsorbents and their application in gas separation, where the design of ligands and the selection of metal ions play a decisive role. Herein, we synthesized two isoreticular Zn-MOFs, UPC-250 and UPC-251, composed of imidazole-based tricarboxylic acid ligands and binuclear zinc clusters. The pore environment was regulated via modifying fluorine atoms at different positions of ligands, and one-step purification of ethylene from acetylene/ethylene/ethane ternary mixture was realized in UPC-251.

The photocatalytic conversion of CO and HO into useful chemicals or fuels over semiconductor photocatalysts is regarded as a promising technology to address the problems of global warming and energy exhaustion. However, inefficient photo-absorption and slow charge dynamics limit the CO photoreduction efficiency. Here, a ternary heterojunction photocatalyst, CuCl(OH)/In/InO (Cu H IO), with an intimate interface is obtained a hydrogen chemical reduction approach followed by hydrolysis reaction, where In species can be produced on the surface of InO from the hydrogen chemical reaction with a calcining temperature of over 500 °C.

Introduction of a guest component into the active layer is a simple yet effective approach to enhance the performance of organic solar cells (OSCs). Despite various guest components successfully employed in the OSCs, efficient guest components require deliberate design and ingenious inspiration, which still remains a big challenge for developing high performance OSCs. In this work, we propose a concept of "structural gene" engineering to create a new "double-gene" small molecule (L-DBDD) by simply combining the structures of both donor PM6 and acceptor L8-BO.

Article Synopsis
- Ternary solar cells are being developed to enhance the efficiency of organic solar cells by adding a third component, though the relationship between morphology and power conversion efficiency (PCE) is not fully understood.
- Researchers constructed two ternary active layers with different Y7 component contents and investigated how these variations affect PCE through theoretical calculations.
- The study reveals that increasing Y7 content shifts the stacking patterns in the active layer, influencing charge separation and enhancing PCE, while also laying groundwork for future experiments involving non-fullerene materials.
